My Amazon wishlist is the largest, most diverse, and is the easiest from which to purchase. The items on this list are varied from just a few dollars to hundreds of dollars and shipping information is already supplied.
You can even use the wishlist to get ideas and purchase items elsewhere. Just mark the item as purchased elsewhere on the Amazon site.
I would prefer to buy from Target over Amazon but, the cart restrictions and availability force me to use Amazon more. That said, Target is local to me and is the best place for household supplies.
Shipping information should be applied automatically at checkout. In addition, you can opt to have the items shipped to the store for pick-up, which may save money by eliminating shipping costs.
